Anthony Mitchell Jr. could be heard sobbing in the background as his mother told a 911 dispatcher that his girlfriend was lying hurt on a trail.

"She was dragged into the trees," the dispatcher overheard Mitchell say as his mother explained how the girl had left their house about an hour earlier to go to a friend's house.

"She never called to tell us she got there, and my son is saying that she's on the trail and that she's hurt," the woman said.

"He went looking for her and found her in the trees. ... He said he couldn't wake her up. He said he tried to give her CPR," the woman told the dispatcher.

One day after Mitchell was charged with two counts of second-degree murder in 16-year-old Anna Hurd's death, Maplewood police released the 911 transcript of the call a woman placed about 4:30 a.m. Feb. 23 that led them to Hurd's body in Hillside Park.

A medical examiner determined that Hurd died of blood loss caused by stab wounds.

Mitchell made his first court appearance Wednesday, March 6, appearing alongside his parents. He is scheduled to be back April 3 for a hearing on whether he can be tried as an adult, as prosecutors are seeking.

Mitchell will remain in custody until then. His attorney asked that he be released to his parents, saying Mitchell has never been in trouble before and has good grades in school.

After the hearing, Patrick Hurd said he felt bad for Mitchell's parents but was upset they had not apologized to him since the arrest. Mitchell's parents declined to speak to reporters after the hearing.

The 911 transcript does not identify the caller, but the juvenile petition filed Tuesday against the 17-year-old said he had asked his mother to call 911.

At some point during the conversation, the woman handed the phone to her son, according to the transcript.

"Was she bleeding or anything like that?" the dispatcher asked Mitchell.

"Yes, it's all over my hands because I tried to give her CPR," he said. "She had no pulse. She wouldn't wake up."

The dispatcher then asked if he had been with his girlfriend, and Mitchell said Hurd had been walking alone on the trail. He said the two had gone to McKnight Market to see whether it was open when his girlfriend decided to go stay at a friend's house and said she would call or text him when she arrived.

When the dispatcher questioned why Hurd would walk by herself on a dark trail, Mitchell said her friend had asked her to come over.

"I shouldn't have let her go alone. ... I would have driven her but I didn't have my car," he told the dispatcher.

"Did you hurt her?" the dispatcher asked.

"No, I just found her," Mitchell said.

"And we have no clue who would have done this to her, right?" the dispatcher asked.

"No, I ..." Mitchell replied, according to the transcript.

Mitchell was sobbing throughout the conversation, according to the transcript.

The North High School senior was arrested March 1, about a week after Hurd's body was found in the park.

She had been planning to move in with her mother in Texas, according to the juvenile petition.

Mitchell, whom two of Hurd's friends described as controlling and jealous, knew his girlfriend was leaving.

When questioned by police, Mitchell reportedly gave inconsistent statements about what happened the night of the slaying.

After denying he had seen anyone else on the path where he discovered her body, he later said he chased a man he had seen standing over her belongings.

He also denied carrying knives, though witnesses at a party he had been at earlier in the night said they had seen him with one.

Hurd's friends said they had heard that the two fought earlier in the night after Hurd had received a text message from an ex-boyfriend.

She also had recently told one of them she wanted to break up with Mitchell but was scared.

Lexi Wallin, 15, said she last heard from her friend about two hours before her body was discovered.
